GDB print binary with leading zeros

Question

I am trying to print a 32bits register within GDB using the command:

define gpioa_moder
    print /t *(uint32_t*)0x48000000
end

This is what I get:

101000000000000000010010100000

However, I'd like to keep the two leading zeros missing like this:

00101000000000000000010010100000

Thanks

Answer 1

You may want to try the x (examine) command.

Then use it like this:

x /w 0x48000000
---> 0x48000000: 00101000000000000000010010100000

You can even use the other format parameters b, h and g to print different sizes.
